I think white noise can be a great way to help comfort an unsettled baby. Babies are used to hearing continuous noise from when they're in the womb and they hear their mother's stomach noises, her heartbeat and other bodily functions as well as talking and other noises in the environment.
 
Hushh is a portable electronic sound machine designed to help baby fall asleep and stay asleep anywhere. The Hushh cradles your baby in soothing sound to create a comforting, consistent sound environment for sleep. compact portable unit comes with 3 sound options: choose from bright white noise, deep white noise, or gentle surf and a wide volume range. The sounds are played on a continuous loop. Hushh is powered by a lithium ion battery and recharges from a micro-usb cord (included). Throughout night time or naptime, it masks disruptive noises to promote longer, more restful sleep cycles. It runs continuously without a timer, and has an on/off button.
 
And the continuous play means you can turn Hushh on at bedtime, and it will help calm and resettle your baby or child all through the night. No timers or need to reset, just lovely calming white noise all night.
 
 Runs continuously for about 12 hours on battery power on medium volume and without the nightlight.
Internal rechargeable battery, so no need to buy extra batteries. Use the USB cable supplied.
Wide range of volume (only have on high if if it is across the room from baby and only for short

The Hushh comes with a one meter USB cable cord, but not a power plug or adapter. The Hushh is intended to be used as a portable machine. Please do not leave the unit plugged into power for an extended period of time as this can damage the internal rechargeable battery. It is recommended that you only use the USB cord provided with your Hushh. Using any other cord can result in damaging your unit and/or does not provide sufficient power to run your unit. We suggest popping a sticker/marker on your Hushh cord so you can differentiate between other USB cords you may have in your household.
